To l/ZZ whom, t may concern:l

Be it known that I, FRANCIS LEONARD OBR, a citizenrof the United States,and a resident of Thurman,in the countyof Freand improved means adaptedfor use with any type ofv similar engine, -whereby With power storedinto a suitable receiver the enpoint of rest of its crank-shaft.

The invention consists of peculiar devices,

and apparatus wherebya portion oi the ex-I ploded or exhaust gases maybe stored under pressure and the'same employed, by means of the peculiardevices, for starting the engine regardless of the position of theenginepiston. In the following detail description of my inventionreference is had to the accompanying drawings, in Which-` Figure lis aview illustratin my invention 4in use, a sectional portion o theenginecylinder, with its piston, being only shown in the view; and Fig.2 is a detail end" view in illustration of the compression-valve-operat'devices. i 'p n the practice of my invention I employ a suitable tank Avand connect it by means of a suitable tubularpassageway B'With thecombustion end ofthe engIne-cyli'nder C. In the passage-wav B, I arrangeany form of compression-va ve D, having aprojecting stem E. Above thevalve-stem E I locate a cam F, having its outer side made conical orinclined, sub- Stantiall as indicated at G. The cam is arrange on aAshaft H, driven through any well-known caring or other mechanicaldevices (not siown) coupling it with the engine crank-shaft I. Infurther carrying out my invention I emplo atubular passageway J,sui'liciently sma ler than the passage- Way B. The passage-Way J isarranged with one end in o en communication with the receiving end o thetube B and its other end connected with the tank A, as shown. In thereduced passa e-'way J I arran e any iorm'of checkd-.valve seating as inicated by the arrow. f

In the latter assage-way I,arrange athree-way valve N, y aving a working handle O and with one openingtherethrough adapted for discharge into the open air at P, as will befully understood Wit out illustration or detail descrip- In the cylinderL, I arrange a piston Q, having a rod R, whose up er or outer end isprovided with rack-teeth S.

The outer end of the piston-rod Ris suitably supported and piovided withthe rackteeth S thereon, in engagement with similar teeth on a segmentalgear T, arranged to turn freelyon the crank-shaft I. A suitable pawl ordog U is provided on the loose gear T, with the same designed forengaging the teeth of aratchet-wheel V,iiedly secured to the crank-shaftagainst its rotation thereon.

For use in connection with the devices last described I provide afixedly-supported `iinger W, with its free end W extended and disposedsuitably for engaging the pawl or dog U, whereby should the engine bestarted intoreverse or backward rotation the pawl Will bethrown from enagement lwith the teeth ofthe ratchet-Wliee V. The iinger W may belocated on an arm A" at the upper end of a suitable standard A2,projecting from the engine-bed.

B denotes a bell-crank having oscillating support at B2 on a projectionA3 from the standard A2. B3 of the bell-crank has pivotal connectionwith the piston-rod R and that its other end B4 is disposed forattachment to the adjacent end of a rod C. In further describing myinvention I would refer to an elongated pin D which may have support onthe rear end of the engine-cylinder C. On this pin I slid-- ably arrangean arm E', through which the adjacent end of the rod C is extended andsecured by jam-nuts F. The free end of the arm E is (provided with aroller Gr and its un- It will be noticed that one end der side isposedresting on the upper end of the valve-pin E with sliding contact, aswill be understood.

' The construction of my invention will be understood from the'abovedescription.

In Fig. 1 of the drawings all the parts of my invention are shownatnormal position. The engine may be stated as standing at' rest withits piston Il leftrat the middle of cylinder ln the. use ot my inventionexhaust-gas or .fxplosi'ye mixture is stored in the tank A underpressure. This may be accomplished by passage ol a portion oli theexhaust-gas into the tank through the pipe J. A ehecl-i-Valve li isarranged in this pipe to prevent return passage therethrough of thestored in the tank. Now when it is desired to st-art the engine inmotion the three-Way yalye 'N is turned7 closing the opening Ptherethrough to open air and at the same time opening up l'reepassage-Way through the pipe M from the, tank to `and into the cylinderli under its piston Q. the cylinder L will force the piston Q upwardlyand through operation of the latter's rod E, the. rack S, toothedsegment '.l`, lpawl "l, and ratchet-wheel Y impart boosting action tothe shaft I, and thereby start rotation 'of the power-shaft l.. NVhenthe boosting action of the power-shaft just. described is made, shouldvthe shaft be started into backeli'eeting the boosting act-ion now fullydej scribed the bell-crank B through attachment of one end B" thereof tothe rack end of the piston-rod R and connection ol' its other end B"with the adjacent end oi'A a rod t" 'valve D Yin the pipe B opens. aswill be. described vl'arther on. ,lt ,is intended that upon opening thevalve D sulli'eient pressure otI gas shall pass from the tank A,vthrough the pipe B, and into the eombustion-chamber of the cylinder (lto torce forward the engine-rusten, and thus start the engine iuoperation. IEnd- Power thusI introduced intov Wise mow-'ement of the rodt" taking place.

upon operation of' the bell-crank B during the boosting actionldescribed will adjust vthe jl arm E on its su i iortine- )in 1) toiosition, h i l with the roller G thereon directly under the lr doubleearn l", and the roller G/ is assured of proper moyement into adjustedposition through means oi' the outer conical-shaped f surface G on theeam. Now the eam-shalt H lla-ying proper gearing or other diiyingconnection with the engine power-shaft, it is l apparent that uponcontinued operation of the cam F and at proper time its action willeilect downward nioyemenl of the `free end ol the arm E" and throughpushing action of the latter against the upper end of the valvestem Eforce open the naive, whereupon pressure and '.,volume of gas will rushthrough the pipe B4 into the combustion-ehamber of the cylinder (l ateach return stroke of the engine-piston for etl'ect-ively starting theengine. In further description of my invent-ion it becomes necessary tosay that when the engine has been started and is under sufficientmomentum the handle O is turned, ad just-ing the passage-ways throughthel valve N, providing free j'assage-way from the un.- der side of lthepiston Q in the cylinder L, through thtl pipe M and opening P of thevalve N, 'to the open air. This operation cuts oil` l'low et' gas fromthe tank A. New pressure being removed from the under side of thepistonQ, it is apparent that the latter will by gravity thereof and itsconnected devices be returned to normal position at the lowr end ot thecylindt r li. 'lhe action of parts just described will through. thelbelli-erankf and rod C force the arm E from under the Acam l" tonormal-position. (Illustrated in Fig. 1 of my drawings.) It willbeunderstood that after manipulation and operation of the starting meansabove described the regular or ordinary power means is used, as with anyengine of this character. t

While the means hereinbefore described is e'll'ectiye for automaticloperation of the Valve l), l do not desire to be restricted thereto,since the same may be materially modified and st ill remain within thescope ot' mynvention, which may be stated as comprehending broadly theuse of a storage-tank, means whereby the engineexhaust-gases or,unexploded mixture may be stored therein .by aetion ol theengine-piston andrleviees wherethrough a Valve in apassage-wayconnecting the .tank and engine-cylinder is opened and closedfor governing feed ott-he stored -gases into the engine-cylinder.
